2 Claims. (01. 2s1" 1) The invention relates to a writing pad equipment as described in the present specification and illustrated in the accompanying drawing that forms a part of the same.

The invention consists essentially of the novel features of construction as pointed out broadly and specifically in the claims for novelty following a description containing an explanation in detail of an acceptacle form of the invention.

The objects of the invention are to provide a strongly built and firm writing pad and supporting table for use with wall telephones in telephone call boxes, in conjunction with speaking tubes of all types, in places where inevitable local vibrationi is present as in railway cars, mo tor buses,'steamships, trucks, airplanes and the like, to furnish a'supporting table having clamping members thereon adapted to receiv the backing of an upper attachable pad of writing or other suitable paper, to provide a support having its front surface sloping outwardly to its lower edge and having an upper place for pencil in conjunction with a finger plate to protect the surrounding wall surfaces and generally to furnish a writing pad equipment which shall'be simple in construction and design, may be strongly built; light in weight, easily attachable to and detachable from existing equipment, and shall be cheap to manufacture and durable and eflicient for its many uses.

In the drawing: 1 1

Figure 1 is a front elevational View of the pad supporting table. I

Figure 2 is a detail elevational View of the upper finger plate.

Figure 3 is an offset cross sectional view on the line 3-3 in Figure 1.

Figure 4 is a right end side elevational view of Figure 1.

Figure 5 is an enlarged fragmentary detailed perspective view of the locking member of the writing pad.

Figure 6 is a fragmentary plan View of the locking member of th writing pad.

Referring to drawing, it will be seen from Figure 1 that the device consists of the outwardly sloping supporting member ID, having two clamping members ll, disposed equidistantly about a central line.

The cross sectional shape of these clamping members II is shown in Figure 3 and their purpose is to retain the backing board [9 of a writing pad l3 which may be inserted therein from the upper extremities I2 of these clamping members I I. Each of the members ll forms a close fitting groove into which the edges of the backing board IQ of the pad [3 are free to slide.

The writing pad I3 is detachably secured firmly to the supporting member ID by means of the locking device's l1 and l8located ata convenient distancefrom the lower ledge l6 of-the writin'g padl3.

The locking member consists of the two intersecting geometrically shaped apertures l1 and 1-8; having the'pronged members 2| and 22 therebetween and suitably-spaced in and through the backing'board IQ of the writing pad'l3.

Secured into the supporting member Ill and in an approximate coincidence with the intersecting geometricallysha'ped apertures l1 and la is a locking pin 20 which has the same geometrical shape as th apertures. It is to be noted that the geometrically'shaped apertures l7 and l'8 are preferably both of a like diameter, slightly smaller than the herni-s'pherical head of the locking pin It will readily be understood that when the pad correctly fits the spacebetween the two clamping members H, the locking is'effected by pushing the two pronged members 2'! and 22, formed be tween the intersecting apertures I1 and I8, down wardly over the centre of the hemi-spherical head of the locking pin 20, so that the pronged members 2| and 22 in their final position arecentrally disposed'and held underneath the head of the locking pin 20. V

In providing two intersecting shaped aper-' tures, a double purpose is served as by this means, suitable flanges are produced.

In commercial manufacture it has been found difficult to ensure absolute rectangularity of the bases of the pads, and to ensure that the clamping members II are absolutely parallel so that it is a very great practical convenience to be able to press the locking pin 20 through either aperture for locking purposes.

As shown in Figure 4 the exterior surface of the supporting member Ill is inclined at a suitable angle from its supporting wall or other member for greater convenience in use.

This inclination is affected by securing a transverse member 23 at a suitable distance from the lower edge which is furthest away from the supporting wall or other member.

This member 23 also has a dual purpose in that it forms a protected shelf for repeat memoranda between the supporting wall or other member and the rear surface 24 of the member Hi.

When the pad and equipment is used in connection with wall telephone apparatus or any other apparatus which requires attachment by screws similar securing means, two horizontally projecting suitably spaced lug members 25 and 26 are secured to the upper back surface of the member Ill and to one outer extremity of the shelf member 23.

The top inclined edge 30 of the supporting member ID is used as a pencil support. The inclination of this edge 30 is affected partly by the slope of the supporting member itself and also by reason of the fact the top edge 30 is itself bevelled so that when firmly fixed in position as in Figure 4, the top edge 30 of the support l forms an angle of approximately 60 degrees with the vertical supporting wall or other surface.

The finger plate member 28 co-operating with the crescent shaped opening 29 approximately in the centre of the top edge 30 of the member In constitutes the upper extremity of the equipment.

The finger plate member 28 is secured to the rear of the sloping member 10 by the attachment means 3|.

It will be noted from Figure 3 that the lugs 25 and 26 are slightly bent so that when pressure is put upon them by any means, the outer edge of the member ID cannot tend to spring away from the supporting surface with which it should be in contact.

It is to be understood that various modifications may be made in this invention without departing from its scope and spirit as defined by the appended claims.

What I claim is:

1. In a writing pad equipment, a base member outwardly inclined and having on the rear surface thereof attachment meansadapted to secure said inclined-base member to arigid backing, said outwardly inclined base member having a shelf member suitably secured to lower rear portion thereof, an upper upwardly projecting finger plate member secured to upper rear portion of said inclined base member and, in combination, adjustable clamping members disposed on each vertical side of a flexible base member of a writing or notation pad member, said clamping members being in substantially parallel relationship to each other on the front exterior surface of said inclined base member, said adjustable clamping members adapted to slidably engage the vertical sides of the said flexible base member of the said writing or notation pad member, and a locking pin member located between the said vertical sides of the said flexible base member of the said writing or notation pad member located on the front exterior surface of the said inclined base member, said writing or notation pad member having a partially flexible base member and said partially flexible base member having intersecting apertures therein, said intersecting apertures forming a plurality of flanges therebetween in diametrical alignment, and said flanges adapted to be engaged by means of said locking pin member in said inclined base member.

2. In a writing pad equipment, a base member outwardly inclined and having on the rear surface thereof attachment means adapted to secure said inclined base member to a rigid backing, said outwardly inclined base member having a shelf member suitably secured to lower rear portion thereof, an upper upwardly projecting finger plate member secured to upper rear portion of said inclined base member and, in combination, adjustable clamping members disposed on each vertical side of a flexible base member of a writing or notation pad member, said clamping-members being in substantially parallel relationship to each other on the front exterior surface of said inclined base member, said adjustable clamping members adapted to slidably engage the verti cal sides of the said flexible base member of the said writing or notation pad member, and a locking pin member located between the said vertical sides of the said flexible base member of the said writing or notation pad member located on the front exterior surface of the said inclined base member, said clamping members and said locking pin member being adapted to secure a writing or notation pad member in a predetermined position relative .to the edges bounding the said inclined base member, said writing or notation pad member having a partially flexible base member and said partially flexible base member having intersecting apertures therein, said intersecting apertures forming flanges therebetween in diametrical alignment, said flanges adapted to be engaged by means of said locking pin member in said inclined base member, said outwardly inclined base member having a crescent shaped opening centrally located in the upper edge thereof, and said upper edge having a bevel thereon throughout its length adapted to form a support,- for pencils and the like in combination with said finger plate member.
